Periodic Nanostructures by “Parquet Floor” Type on InP Surface

We report on the synthesis of the periodic nanostructures of ‘parquet floor’ type on the surface of single-crystal indium phosphide. The structures were formed by electrochemical etching with the subsequent electrochemical deposition. The obtained structure is characterized by a well-ordered displacement of the nanowires in the longitudinal and transverse directions. It was studied that the nanowires consist of porous oxide. A qualitative explanation of the electrochemical processes that occur at the electrolyte/semiconductor boundary during electrochemical treatment is presented. The obtained structures can be applied as photonic crystals and require further studies.
